MICHAEL J. GAHAGAN, OF SAXONVILLE, MASSACHUSETTS.

CARDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 733,383, dated July 14,1903.

Application filed December 26, 1901. Serial No. 87,178. (No model.)

T0 (0 whom it may concern.-

Be it known that 1, MICHAEL J. GAHAGAN, a citizen of the United States,residing in Saxonville, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements inOarding-Machines, of which the following is a specification.

In this invention the Apperly feed is done away with and my improvedmechanism is substituted therefor, the principal object of suchimprovedmechanism being to enable the continuous sliver or roving to bepresented to the feeding mechanism endwise or end on instead of beingpresented in folds and to be fed by the feeding mechanism in the samemanner, thus doing away with the folds or knuckles in the sliver. Bydoing away with these folds or knucklesthat is to say,by not doublingthe sliver-bunching is avoided and there is no waste at the outer edges,as the sliver is entirely fed endwise without projecting at either edgeand with less traverse than is the case in the Apperly feed.

The nature of the invention is fully described below and illustrated inthe accompanying drawings, in which Figure 1 is a longitudinal verticalsection or sectional view of a sufficient portion of a carding-machineto illustrate my invention. Fig. 2 is a front elevation of the feedingmechanism. Fig. 3 is a plan view of the same.

Similar letters of reference indicate corresponding parts.

A represents portions of the frame, and W a portion of the cylinderprovided with ordinary card teeth or clothing. Mounted in this frame atB is the tumbler B, and mounted in advance of said tumbler at O is thedofier C, and mounted in the same frame in advance of the doffer at D isthe deliveryroll D. Above the tumbler is mounted at E the stripper-rollE, and mounted in the same frame intermediate with the tumbler B anddoffer C, above and below the same, respectively, at F and G, are thestrippers F and G. Mounted in the frame above the delivery-roll at H isthefancy-roll H. These rolls are all placed with relation to each other,as indicated in Fig. 1, the teeth or clothing on the tumbler being incontact with the teeth on the cylinder, the clothing on the strippers E,F, and G being in contact with the clothing on the tumbler B, theclothing on the strippers F and G being in contact with the clothing onthe tumbler B and dofier C, and the clothing on the fancy-roll H beingin contact'with the clothing on the delivery-roll D. The clothing on thetumbler and doffer are not in contact or engagement with each other.

J and K are respectively upper and lower feed-rolls or drawing-in rollssplined on horizontal shafts J and K, respectively, and adapted to slideendwise or horizontally on said shafts. These shafts have bearings attheir opposite ends in boxes L, supported by brackets N N, and the saidshafts have respectively mounted on one end intermeshing gears 01- Ct,the upper shaft being driven by a suitable pulley Z). (See Figs. 2 and3.) Mounted on one of the brackets N, Figs. 1 and 3, is a shaft or studc, driven by a suitable pulley d and provided with a bevel-gear c, whichis in engagement with a similar gearfon the shaft or stud g, mounted onthe same bracket. The opposite end of this shaft '9 is provided with asprocket-wheel h, which is connected by the chain P with asprocket-wheel Z on a stud Z, mounted on the bracket N at the oppositeside of the machine. A horizontal engaging pin R extends from this chaininto a vertical slot Vin the hanger or portion S of the carrier ortraveler S, through which the shafts J and K extend and between the thesides S of which the rolls Jand K are located. The lower end of thisportion S is formed into the trumpet T. The sliver is fed endwisethrough the trumpet T between the rolls J and K. These rolls arehorizontally placed, and consequently rotate'on a vertical plane, theirrotation being inward by reason of the gears a and a on the shafts J andK, to which said rolls are slidingly secured. The chain B moves thecarrier S back and forth on the shaft J and K by means of the pin R inthe slot V, and thus reciprocates the rolls J and K horizontallyin frontof the deliveryroll D. The sliver is therefore fed end on to thedelivery-roll for substantially its entire length, vibrating back andforth horizon tally, but always presenting its end, (not its side,) andhence never presenting any folds or knuckles. The sliver having been fedto the delivery-roll, the fancy-roll H in engagement with the.delivery-roll brushes it off,

and the sliver is conducted to the dofifer 0, whose teeth are in meshwith the deliveryroll. From. the doffer the sliver is conducted, bymeans-of the upper strippers F E and lower stripper G, to the tumbler B,which delivers it to the cylinder XV. Thus the sliver is fed byhorizontally-placed, verticallyrotating, and horizontally reciprocatingfeed rolls without folds or knuckles and thoroughly distributed on itsway to the cylinder without waste with a comparatively short traverse ofthe feed-rolls, a knock-off being unnecessary. The sliver on its path tothe cylinder passes from the feed-rolls J K to the delivery-roll Dbetween it and the fancy-rollH, thence to the doffer C, from which it istransferred above and below,respectively, by the strippers F and E and Gto the tumbler B, from which it passes to the cylinder.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

In a carding-machine, the frame, and cylinder \V; the tumbler B anddofier U mounted in the frame, the tumbler in advance of the doffer andthe teeth of said tumbler being in mesh with the clothing on thecylinder; the

delivery-roll D in mesh with the dolfer; the stripper-roll E above andin mesh with the tumbler; the stripper-roll F above and in mesh with thetumbler and the doffer and also with the stripper-roll E; thestripper-roll G below and in mesh with both the tumbler and the dofier;the fancy-roll Habove and in mesh with the delivery-rollD,all said rollsbeing provided with suitable clothing and being mounted in the frame,and the fancy-roll and strippers being comparatively small in diameter;upper and lower feed-rolls adapted to slide horizontally on theirshafts; means for rotating said feed-rolls, traversing mechanism forreciprocating the feed-rolls horizon tallyin front of the feed; thecarrier S inclosiug the ends of the rolls, slotted at V, and providedwith the trumpet T; and mechanism for recipro: cating said carrierhorizontally in front of the feed, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

MICHAEL J. GAHAGAN.
